GOLANG读取配置文件（简易版）

将文件中的键值对(去空格)转化为map使用
例:配置文件application.properties

   host=  127.0.0.1
port=8080
database=mysql
username=admin
passwd=123456

代码

package main

import (
        "bufio"
        "fmt"
        "io"
        "os"
        "strings"
)

var properties = make(map[string]string)

func init() {
        srcFile, err := os.OpenFile("./application.properties", os.O_RDONLY, 0666)
        defer srcFile.Close()
        if err != nil {
                fmt.Println("The file not exits.")
        } else {
                srcReader := bufio.NewReader(srcFile)
                for {
                        str, err := srcReader.ReadString('\n')
                        if err != nil {
                                if err == io.EOF {
                                        break
                                }
                        }
                        if 0 == len(str) || str == "\n" {
                                continue
                        }
                        properties[strings.Replace(strings.Split(str, "=")[0], " ", "", -1)] = strings.Replace(strings.Split(str, "=")[1], " ", "", -1)
                }
